of .my invention.

Referring further to the drawing, my im proved whiffie tree comprises atubular bar 5, a brace-block 6, preferably made of wood, extending longitudinally of the bar and centrally between the ends thereof, a truss-rod 7 brace-block and projecting through and beyond the ends of the hollow bar, nuts 8 on the threaded eX- tremities of the truss-rod, bearing upon'the ends of the main bar, guard pieces 9 applied and secured by the nuts, and a reinforcing piece 10 embracing middle portion of the device.

The brace block is concaved at one edge to provide aseat for the tubular bar, the portion 7 of the truss-rod engaging the opposite edge of the block,'is flattened and the bar, the block and the red are secured to-, gether by rivets 12. The reinforcing 'member 10 is of U-shape and embraces the mid- ,dle portion'of the bar and-the brace block. 7 10 is fastened on the block by' he member means of rivets 13 and it has 1n its two legs, apertures 14' in alinement with a hole 1n the 19.2.6- se l NO- ibaosa brace block for o the applicationbf a ring or clevi sto' attach thedouble'tree to atongne a veh l om e fi new r ele implement, or o s cu e the ing e tr es a ends of the double tree.

7 Having thus described my invention, it will be apparent that the elements of which it is composed, cooperate to provide a rigid and strong structure well adapted to withstand the most severe stresses. The reinforcing member 10 prevents the strains from being entirely directed to and borne by the truss-rod and it furthermore provides metal.
